monitoring user events number

[User002]

Salut.

Is it possible to monitor the number of user events that have been fired in an application? Kind of like a queue monitor?

Hi

I've just made a simple vi, where you can see which event occured. There's a string indicator, in which a text is displayed. The text is generated inside the event case. In the event case of the string control, I also read the type of event and pass this also to the string indicator.

I don't know if this is what you need, but maybe it helps you.

One way of doing it is to base your application on Producer/Consumer Design Pattern (Events) design pattern.

You can do this by going to File -> New ... -> VI From Template -> Design Patterns -> Producer/Consumer Design Pattern (Events)

In this design pattern you would pass over the event handling from the producer loop to the consumer loop. You then add in another quile loop to monitor the queue status.

Good presentation on Design patterns http://zone.ni.com/devzone/learningcenter.nsf/webmain/338EE44CB1C3450986256C2B007CF8C5

Simple example attached. I think you will need Labview 7.0 Full Development System upward for this feature.

Hope this helps

Labview 7.1 on XP.

Salut.

The software is already built around the producer/consumer/capitalist concept. It is using "programmatic user event/event structure" as the building block. The producer registers the event and i would like to be able to monitor how many events have been registered. Possible?

Hi J...

I haven't looked in detail so this is off the top of my head....

Wouldn't the interation counter for the while loop that holds your event structure tell you how many events have been fired since the application was started?
